Grindersare used for cutting or shaping metal parts and providing
the properly finished surface. Drives or Motion products are used
to maintain constant grinder wheel speed during all phases of the
process.

Application Challenges

SpeedMaintain constant grinding surface speed

EfficiencyGrind at optimal efficiency while doing heavy or light grinding

Electronic GearingFollow an external encoder to synchronize conveyor with other
sections of the process

Adjust torque to optimal performance as grinding stone dulls or
clogs

Avariable-frequency drive (VFD) is a system for controlling the
rotational speed of an alternating current (AC) electric motor by
controlling the frequency of the electrical power supplied to the
motor. A variable frequency drive is a specific type of
adjustable-speed drive. Variable-frequency drives are also known as
adjustable-frequency drives (AFD), variable-speed drives (VSD), AC
drives, microdrives or inverter drives. Since the voltage is varied
along with frequency, these are sometimes also called VVVF
(variable voltage variable frequency) drives.
